Cells Flashcards
What 2 types of microscope can be used to enable us to see cells
A light microscope and an electron microscope
which microscope gives the most detail
electron microscope
what is the calculation to work out the magnification of a light microscope
total magnification = magnifying power of the eyepiece lens x magnifying power of the objective lens
what term is used to identify the power of a microscope
resolving power
what is the difference between a light microscope and an electron microscope
Light - uses beam of light to pass through the cell
Electron -uses beam of electrons through the cell
What is the formula for the resolving power
resolving power = wavelength / 2
what is the name for organisms made of many cells
multicellular
Name the 4 components of an animal cell
Cell Membrane
Nucleus
mitochondria
cytoplasm
Name the additional 3 components of a plant cell that an animal cell does not have
Cell wall
chloroplast
vacuole
What happens in the cytoplasm
most of the cell’s chemical reactions take place here
What does the cell membrane do
Controls the movement of chemicals in and out of the cell
What does the nucleus contain
Chromosomes
What happens in the mitochondria
sugars are broken down releasing energy
what does the cell wall do
strengthens the cell
what does the vacuole do
Keeps the cell turgid (swollen/inflated/solid)
